[0025] The technical solutions in the embodiments of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Reference Figure 1-Figure 7 The utility model provides an embodiment: a handheld shovel-type tool, including a support rod 2, one end of the support rod 2 is fixedly connected to a dust removal block 1, a dust removal slope 102 is provided on the side of the dust removal block 1 away from the support rod 2, the other end of the support rod 2 is fixedly connected to a fixing sleeve 3, the outer side of the fixing sleeve 3 is threadedly connected to a connecting sleeve 4, the upper part of the connecting sleeve 4 is fixedly connected to an elastic clamping tube 501, the outer side of the elastic clamping tube 501 is threadedly connected to an adjusting nut 5, an auxiliary dust removal structure is provided inside the elastic clamping tube 501, the adjusting nut 5 can be raised and lowered when the outer side of the elastic clamping tube 501 is rotated, so that one end of the elastic clamping tube 501 can be contracted and opened, and the auxiliary dust removal structure can be clamped and released.

[0027] Among them, the support rod 2 can be made of solid light stainless steel bars with a diameter of 10-20mm and a length of 1.5m-2m. It is preferably a stainless steel bar with high hardness, light weight, rough surface and easy to hold. The dust removal block 1 can be made of a flat iron block or steel block with a length of 10cm and a width of 5cm. It is preferably an iron block or steel block that is easy to grind and has high hardness. The support rod 2 is combined with the dust removal block 1 by welding. According to the actual construction requirements, the dust removal block 1 head can be ground thin to form a dust removal slope 102, so that the contact surface with the scale block becomes smaller, the grinding resistance is reduced during use, thereby further reducing manpower. When in use, hold it with your right hand. Hold the support rod 2 with four fingers of the left hand about 50cm away from the dust removal block 1. The dust removal block 1 and the surface of the vibrating feeder groove form an angle of 20°-30°. Place the support rod 2 on the lower right side of the lower abdomen. When cleaning the scale blocks, press the dust removal block 1 downward and push the support rod 2 forward with the body. When the scale blocks are relatively solid, use the auxiliary dust removal structure in the opposite direction to knock them repeatedly, so as to improve the problem of dust on the surface of limestone falling into the vibrating feeder groove and causing serious scaling of the vibrating feeder. The advantages of the utility model are exquisite and reliable structure, repeated use, easy use, shortened construction period, improved work efficiency and reduced cost.

[0028] refer to Figure 3 A dust removal blade surface 101 is provided at one end of a dust removal slope 102 adjacent to one side of the dust removal block 1. The dust removal slope 102 can be thinned at the head of the dust removal block 1 to reduce the contact surface with the dirt block, thereby reducing the grinding resistance during use and further reducing manpower. The design of the dust removal blade surface 101 makes one corner of the dust removal block 1 sharper, which is conducive to removing dirt.

[0029] The support rod 2 has a diameter of 10-20 mm and a length of 1.5 m-2 m. It adopts solid light stainless steel bars, and the dust removal block 1 adopts a flat iron block or steel block with a length of 10 cm and a width of 5 cm. The support rod 2 and the dust removal block 1 are combined by welding.

[0030] The thread direction of the outer side of the fixing sleeve 3 is the same as the thread direction of the outer side of the elastic clamping tube 501. The connecting sleeve 4 is threadedly connected to the outer side of the fixing sleeve 3, and when the adjusting nut 5 is turned to tighten the elastic clamping tube 501, the connecting sleeve 4 is prevented from falling off from the fixing sleeve 3.

[0031] refer to Figure 4 A separator 401 is provided in the middle of the connecting sleeve 4, one end of the elastic clamping tube 501 is fixedly connected to one side of the separator 401, and one end of the fixing sleeve 3 abuts against the other side of the separator 401. The separator 401 divides the connecting sleeve 4 into two chambers, which can play a limiting role and respectively accommodate the fixing sleeve 3 and the elastic clamping tube 501.

[0032] The elastic clamping cylinder 501 includes four elastic strips, one end of which is integrally formed and connected to one side of the separator 401, and the other end of which is distributed inside the adjusting nut 5 and is open. External threads are provided on the outer sides of the elastic strips, and the elastic strips are threadedly connected to the inner side of the adjusting nut 5 through the external threads. When the adjusting nut 5 rotates on the outer sides of the four elastic strips, since the adjusting nut 5 is threadedly connected to the elastic strips, the forward and reverse rotation of the adjusting nut 5 can achieve the lifting effect, and the longitudinal section of the elastic strip is trapezoidal, and the lifting of the adjusting nut 5 can achieve the tightening and opening of the four elastic strips. When the adjusting nut 5 descends and approaches the separator 401, one end of the four elastic strips opens, and when the adjusting nut 5 moves away from the separator 401, one end of the four elastic strips can shrink, which can achieve the tensioning and loosening of the auxiliary dust removal structure, and realize the rapid installation and disassembly of the auxiliary dust removal structure.

[0033] refer to Figure 4 and Figure 5 In one embodiment, the auxiliary dust removal structure includes a dust removal rod 6, one end of which is placed in the elastic clamping tube 501, the other end of which is provided with a pointed head 602, and both sides of the dust removal rod 6 are provided with arc surfaces 601. When the scale blocks are relatively solid, the design of the pointed head 602 and the arc surface 601 can play a knocking role to improve the descaling effect.

[0034] In another embodiment, the auxiliary dust removal structure includes an L-shaped rod 7, one end of the L-shaped rod 7 is placed in the elastic clamping tube 501, the other end of the L-shaped rod 7 is fixedly connected to a dust removal plate 701, both sides of the dust removal plate 701 are fixedly connected to inclined plates 702, and the other end of the L-shaped rod 7 is provided with a dust removal triangle plate 703, and the adjacent sides of the two inclined plates 702 are respectively fixedly connected to the two sides of the dust removal triangle plate 703. When the scale blocks are relatively solid, the dust removal triangle plate 703 can play a role of scraping and cutting to improve the descaling effect. The auxiliary dust removal structure can adopt the above two methods, and according to the actual situation, the adjustment nut 5 can be turned to quickly replace different auxiliary dust removal structures to improve the descaling effect.

[0035] The central axis of the dust removal plate 701 is parallel to the central axis of the support rod 2, and the mid-perpendicular line of the dust removal triangle plate 703 is parallel to the central axis of the dust removal block 1. The above design facilitates the dust removal triangle plate 703 to play a scraping and cutting role when the support rod 2 is pushed to move.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
